The new Plextor M5 Pro Xtreme 256GB is a very good offering, but it still doesn't put Plextor into the top performance tier with Samsung's 840 Pro and OCZ's Vector, at least not in this capacity size. We added the last bit to the sentence because Plextor's custom firmware has always done very well in the lower capacity sizes, especially the 128GB size. Soon we'll have the 128GB M5 Pro review with new 1.03 firmware published and see how it fairs.
The M5 Pro Xtreme 256GB does cost less than 840 Pro and Vector and that makes up for the slight decrease in performance. All three drives in this capacity size are smoking fast and I doubt anyone would feel a difference while in use. The benchmark tests highlight the micro differences and they appear much larger than what you would notice in the real world, but for some that matters.
Plextor did raise the bar of their products with the new Xtreme drives. The new NAND flash also produces a nice increase in sequential performance, but at the cost of random performance. The sequential increase easily outweighs the small loss of random performance though since you will actually notice the sequential boost.
When push comes to shove though, you would be fine purchasing either M5 Pro product. The real world differences are not that great but then again, the file transfer increase when writing data to the drives is worth the $10 premium. We'd like to see Plextor lower the price of the Xtreme 256GB to at the very least the same $209.99 that we found the M5 Pro at. That price would make the Xtreme 256GB much more attractive and easier to choose over the Samsung's class leader.
